Have you ever experienced trouble starting your Nissan or Infiniti vehicle, only to be greeted by an error message saying “key incorrect” or “no key detected”? It can be frustrating and inconvenient, especially when you know that it is the correct key for your car. In this article, we will discuss a simple and fast fix for this issue that you can follow to get back on the road or to the nearest store to buy a new battery.

Identifying the Problem

A customer recently brought their car to me, explaining that everything seemed to be working fine except for the key detection. When he tried to start the car, it would not detect the key. However, upon inspection, it was clear that he was using the correct key and pressing the brake pedal correctly. This led me to conclude that the issue was most likely related to a dead battery in the key fob.

Quick and Easy Fix

To fix this problem, you will need to replace the battery in your key fob. The battery used in most Nissan and Infiniti key fobs is a CR2032. You can easily find this battery at an auto parts store like AutoZone or even at RadioShack. Here are the steps to follow:

  1. Open the key fob: Using your nail or a small tool, apply gentle pressure to the designated area on the key fob to open it. It should easily snap open, revealing the battery compartment.

  2. Replace the battery: Take out the old battery (CR2032) and insert a new one in the same orientation. Make sure to place it correctly; otherwise, it may damage your remote.

  3. Close the key fob: Align the two halves of the key fob and press them together until you hear a click. This indicates that the fob is securely closed.

  4. Test the key fob: After replacing the battery, try pressing the buttons on the key fob to check if the door locks respond. You should be able to cycle the door locks without any issues.

Additional Information

  1. Security Key: Many people are unaware of the existence and purpose of the security key, which is located inside the key fob. This key can be used when your remote’s battery dies or your car battery dies, preventing you from opening the car. Simply slide out the security key and use it to unlock the door. It is a handy feature that can save you in emergency situations.

  2. Proper Battery Placement: When replacing the battery, it is crucial to ensure that you insert it in the correct orientation. Placing it upside down can cause further issues and potentially damage your remote. Take your time and double-check before closing the key fob.

  3. Error Messages: Once you have successfully replaced the battery in your key fob, you should no longer encounter error messages such as “no key detected” or “incorrect key.” Your vehicle will be able to detect the key properly, allowing you to start the car without any issues.

In conclusion, if you are facing a “key incorrect” or “no key detected” error message when trying to start your Nissan or Infiniti vehicle, the most likely cause is a dead battery in your key fob. Follow the simple steps outlined in this article to replace the battery and resolve the issue. Remember to insert the new battery correctly and test the key fob to ensure that the door locks respond as expected. With this easy fix, you can confidently get back on the road and continue with your day hassle-free. Stay safe and take care!
